' Application filed May 12,1917. Serial No. 168,182.

To all whom it may concern:

Be it known that I, WILLIAM L. Born, a citizen of the United States, and resident of Hayden, in the, county of Gila and State of Arizona, have invented certain new and use.- ful Improvements in Smoke-Purifiers, of which the following is a specification.

This invention relates to new and useful improvements in smoke purifiers, and the primary object of the invention is to provide a device of this character through which the smoke is forced to purify the same, and remove therefrom the solid products of combustion, which are adapted to be used for various purposes, and which were heretofore carried off by the waste gases.

This invention particularly relates to a novel apparatus for purifying smoke which comprises a .novel arrangement for forcing.

smoke through a body of water and agltating the body of water to break up and destroy the globules of smoke and gases passing therethrough to insure the separation of the minute solid particles or products of combustion from the globules formed of and secure the precipitation of the solid particles in the body ofwater and prevent their escape with the gaseous products. The apparatus is furthermore provided with means for withdrawing the precipitationof these solid particles, so that they adapted to. be used for various purposes as desired. A further object of the invention is to provide smoke purifying apparatus of this character which includes a liquid containing portion having the purifying apparatus contained therein, and means for maintaining a predetermined liquid level in said portion during the operation of the apparatus. Still another object of the invention is to provide a device of this character that includes a liquid container provided with means for precipitating the solid products of combustion in the bottom thereof as the smoke passes thercthrough, and an overflow whereby the said products are carried from the container to any desired place.

Another object of the invention is to provide a device of this character which is easily and simply constructed, inexpensive to manufacture, and one which will be very efficient In operation. TJith these and numerous other objects in view my invention consists of the novel features of construction, combination and arshown in section;

, damper control chamber 1, which .outlet 6 of said body. This or any rangement of parts which will be hereinreferred to and more particularly pointed out in the specification and claims.

In the accompanying drawings:

Figure 1 is a vertical section device; 1

Fig. 2 is a side elevation of the water inlet, and automatic control means for the same, 'a portion of the stand pipe being Fig. 3 is a side elevation of the overflow pipe that is connected-with taining chamber; I

Fig. 4 is a vertical section through the apparatus;

Fig. 5 is a detailed transverse through the smoke duct, and

Fig. 6 is a detailed transverse section through the agitators and battles that are disposed in the liquid container or chamber.

In describing my invention I shall refer to the drawings in which similar reference characters designate; corresponding parts throughout the several views/ The device consists primarily of a liquid containing has one end thereof connected'with a smoke flue or chimney 2, said flue being provided with automatically controlled draft regulators 3, which will be hereinafterdescribed more specifically. The container or chamber 1 is divided parts, the inlet portion being by the'numeral 4, and inclined, while the other portion 5 thereof is disposed. vertically, and is provided with a main outlet tlin the top thereof. Disposed adjacentfthe inlet of the liquid. container, and communicating with the smoke flue 2 is a by-pass 7, which extends upwardly, and is connected with .the

section trolled by a pair of flap valves 8, which are adapted to either cut 0d the urifying chamher, or the by-pass, as desire so as to direct the smoke through either one or the other.

The liquid containing chamber 1 is adapted to be filled with water to, a predetermined level, and projecting in through the portion 4 of said chamber are a plurality of parallel disposed. smoke ducts 9, which have their upper ends contracted as shown at 10, and communicating with the outer end of said portion, and with the smoke flue2. "Positioned in the portion 10 of the ducts, are a pair of fans, which are driven by a motor, other desired means, one-fan being designated by the numeral 11 comprising the Patented Apr; is, was

the liquid conby-pass is con- I through the into two designated filo-aim. fan, and a smaller lacs 12 being sated the relay for forcing the smoke from tlie flue throng. the elects and late the chamber 1. This construction will create a sobmergecl clrefrt, so that the sroolre drawn from the fine will be driven through the ill ducts the ducts being surrouncletl by liqiiicl which acts as a, cooling agent therefor and as the lower imier ends oi ducts terminate adj scent the bottom of the chem l, the smoke will be projected or clriven therefrom within the liquid. The terminal of the ducts Sa-re 'ourvecl slightly upvvertlly and they are adapted to dlIGC-ilbllfi smoke discharged therefrom into contact v with the primry purifying means.

This primary purifying means comprises I a lurs-fit oi verticell spaced rows oi a 'ii y i.

tators which ere ioi'meil of disks l3 mountecl on a horizontally extending axis 14, said having a plurality of: teeth in the to riplieral eole'es thereof, and the axis on which the clisss are mounted being revoluble, by means of a motoror any other drive mecbeiiism connected therewith, so that the rlisks will be continually rotated to agitate the Wster for e purpose which will be here more fully described. Spaced between the clislrs 13 are diagonally arraiig erl bellies 16 Which extend inweroly from the opposite sides of the portion 5 of the liquid coiitaiioer. These set-s o'l agitators and beirlisposerl within the portion 501:

saiol container beneath. the water level, and arranged in tlie top'or the chamber above the water level, end in the outlet 6 are oddi- 1 tioroal imverclly projecting inclined bafiies 17 which will supplement tlie primary actiore of the bafies ancl agitstors that merged within the chambe a The bottom of the llqlllfii containing chamare subber its provided with spaced outlet and inlet ope iings, one of which is designated by the numeral 18, and. the outlet opening is ccmiecfiecl with astand @ipe 19, by a short length pipe 20, as clearly shown in Fig. 3 the drawings, the said overflow being 'carrierl through the pipe 20 and up the stand pipe 19,, flowing" over the upper edge'tliereoi and caught in a basin 21 over. which saifcl pipe is positioned, The lower end of the pipe 19 is provided with a valve 22,

which is normally slightly open, we which is adapted to cetcli the solicl products of opwerclly tberetbsroiigb and having a fulcriitcetl em 27 cooiiecteol therewith on'its ELEEJBF The inlet 23 of the pipe 24: is also connected with it stand pipe 28, and positioned within said stand pipe is a fioat 29 connects/cl with the cable which is trainedi over a pair of pulleys in the upper end or saicl stand pipe and secured to one end of the 'l'olcriimecl arm 2? on the upper end of the valve 26. This end of the arm is also provided with a counterbalancing weight 31, anol it is obviousv that upon the operation of this construction the valve 26 will be automatically operated to control the emcee and hence the flow of liquid to the container 1. The water level within the stand pipe 28 is approximately the water level within the chamber, said stand pipe being disposed. adjacent one side thereof. It is'obvious that upon the Water level in the chamber being lowered the water will be lowered in. the pipe 28, and. the float will drop therein, and raise the arm 2'4, hence lifting the valve anal allowing more water to flow through the pipe 24% ancl pipe 23 to tlie costaiiieir or chamber 1. lVben the pre determined water level has been reached, the valve will. be once more automatically closed, by the lilting within the stand. pipe, and the weight 31 pulling the arm 27 downwardly, and hence closing the valve.

The smoke flue 2 is provided with a pair of diametri ally positioned. draft controlled inlets 3, Sam inlets being formecl' with beveletl walls are positioned inopenings in well saizi flue, that are likewise bevelecl, so clearly shown in Fig. 4: of the drawings, The draft controlling devices '3 which act as closures are hingedly connected with the well of the flue, asshown at 32, and the same are adopted to swing ir'iwardly, they however. being normally closed by means of a support 33 secured to the outer face thereof, and. leaving a weight so carried thereby. To limit the inward swinging movement of theclosure 3 a projecting arm 35 on the inner siiriace thereof is provided having on eye 36 on its outer end adapted to slicle on a hinged rod 37 securecl to the inner wall of saicl flue. The rod iii-has a locacl 38 ()ll its outer encl, to limit the inwardly swinging movement of said closure. Tliese draft devices will be automatically ogoeratecl, when the draft is suliicient to draw them inwardly by lifting the Weight 34. As soon as released, the weight 34 will autometically swing them back to closed posi-' tion.

lie operation, when the valves 8 are so positioned, as to close the by-pass 7, smoke from the fine 2 will be directed into the chamber ll. Tbissmoke i drawn into the smoke ducts '9 by means ofthe fans 11 and 12, we. as the same passes through the pare ducts wlicbiorm separate iso s earer passages, Within the portion 4 oi? said sham her, the liquid of the chamber will act as a cooling agent, a and as thesinoke is discharged from the inner ends said ducts adjacent the bottom of the chamber 1, the heavier particles will be deposited in the bottom of the chamber The smaller par ticles consisting of minute solid particles or products of combustion will be carried up- Wardly through the portion 5 of the chamher through the liquid in small globules, and to break up the same the agitators and battles submerged Within the liquid are employed. This will cause the minute particles or solid products of combustion to be deposited or precipitated in the bottom'of the chamber 1, while the gaseous products of combustion will pass upwardly through the chamber, and out the outlet 6. The baiiles 17 will supplement the action of the agitators and battles that are submerged within the portion ,5 of the chamber. By this means the smoke will be purified, and all the solid and valuable products will be precipitated in the bottom of the chamber 1.

The overflow attachment to the chamber 1, will carry the solid products of combustion through the outlet, and hence in a manner hereinbciore fully described the same will be carried to a basin, which receives the same, and iencc they may be transported to any desired place. Swing to the fact that the liquid is constantly flowing from the chamber l, carrying the solid products of combustion therefrom, tnechamber is provided with an automatic liquid inlet, which maintains a predetermined water level contantly therein. The smoke due is provided. 'lth automatic lly controlled draft rcgulaare, the operatic of which has been here before fully ClGSCl' purifying device to be cut oil, upon ration of the 8, when it is desired 0 clean "he interior of the same. The portion 5 provided h door, designated by ;.-.meral 39, whei by access to the interior of the chamber may be easily obtained The spaced rows of agitators that are submerged in the portion 5 of the chamber 1 are adapted to rotate in opposite directions, that is the upper and lower rows or disks agitating in one direction, while the center row agitates oppositely therefrom, This will thoroughly agitate the water, to. accomplish des1red purpose. The various parts used in this apparatus are formed of suitable material, sot-hat they will not corrode or under the action of the gases that pass therethrough.

The operation of this type of smoke purifier will obviate the smoke nuisance, and enables bituminous coals to be used invarious kinds of furnaces, for instance smelting fur- :bed. The by-pass "I alnaces, in municipalities where anti-smoke laws are in force, The purifying apparatus also retrieves the valuable solid products of combustion that were heretofore carried off by the gaseous products and wasted.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and the method of operation will be readily'apparout to those skilled in the art towhich the invention appertains, and while I have de' scribed the principle of operation of the in vention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shownvis merely illustrative, and. that such changes may be made when desired as are within the sco e of the claims appended hereto. c

Having 'fully' described my, invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a smoke purifier the combination with a liquid containing chamber, a smoke duct terminating adjacent the bottom thereof, means for forcing smoke through said duct, an outlet in the top of said chamber,
